Raptors don't have to tank, just play good basketball.. the better Demar and Val play the higher their value will increase.. then you go into the draft with options

We have money getting rid of Rudy Gay's contract, our guys are young and they are winning.. nothing is wrong with that

yes we do have to tank, this draft is, by far, our best chance of getting a star. If we miss out this draft, next year we'll be too good, free agency is unlikely to be the answer and our only option would be to somehow get really lucky and land a star late in the draft OR trade for one, which, at best, will mean losing a number of good assets, not to mention it's so rare to see truly good players traded.

So, on one hand you have finding a way to lose maybe 10-15 extra games this season and almost certainly land a star, or roll the dice on some very low chance alternatives.
